The objective of this study was to examine the development of derivational morphological structures in the productive language of Kuwaiti Arabic (KA)-speaking children. Participants were 512 typically developing Kuwaiti children aged 3;0 years to 7;11 years (243 boys and 269 girls). Five age groups at 1-year intervals were tested; each group was…

Complex systems of inflectional morphology provide a useful testing ground for input-based language acquisition theories. Two analyses were performed on a high-density (12%) naturalistic sample of two Polish-English children's (2;0 and 3;11) and their parents' use of Polish noun inflection: first, each child's use of inflectional affixes and their…

Closely related Swedish and German both mark information status of referents morphologically, though little is known about its acquisition. This study investigates character introductions in the narratives of 4- and 6-year-old Swedish-German bilinguals (N = 40) in both languages, elicited with MAIN "Cat/Dog." We analyse effects of age…

It has long been known that children may use a particular grammatical morpheme inconsistently at early stages of acquisition. Although this has often been thought to be evidence of incomplete syntactic representations, there is now a large body of crosslinguistic evidence showing that much of this early within-speaker variability is due to still…

This research analyzed adequacy of referential expressions in the narratives of bilingual and monolingual children with Developmental Language Disorder (DLD) and typical language development (TLD), aiming to shed light on the relative contribution of morpho-syntactic, discourse-pragmatic, and semantic constraints. Narratives were collected from 51…

The syntactic structure of sentences in which a new word appears may provide listeners with cues to that new word's form class. In English, for example, a noun tends to follow a determiner ("a"/"an"/"the"), while a verb precedes the morphological inflection [ing]. The presence of these markers may assist children in…

Noun-related morphosyntax has not been emphasized in the literature on children with specific language impairment (SLI), yet, across languages, problems in this area are quite apparent. This review is designed to highlight noun-related difficulties that seem to be especially troublesome for these children. A review of the research literature on…

This corpus-based study provides a baseline of complex word usage patterns in the spontaneous speech of English preschool children to ascertain the characteristics of their derivative vocabulary before literacy development affects language skills. Frequencies of suffixed derivatives produced by (N = 243) children aged 2-5 and their caregivers were…

Imageability is the ability of words to elicit mental sensory images of their referents. Recent research has suggested that imageability facilitates the processing and acquisition of inflected word forms. The present study examined whether inflected word forms are acquired earlier in highly imageable words in Czech children. Parents of 317…

This article reports on an experiment that examined the comprehension of transitive sentences in Czech children and its relationship to case marking, word order and information structure. A total of 107 Czech children aged 2;9-4;5 were tested for comprehension of noun-verb-noun sentences in which word order and given-new status of individual nouns…

In her valuable commentary, Kerkhoff raises several issues, both empirical and conceptual. In particular, she argues that morphophonological regularities represented in associative memory might suffice for the acquisition of French grammatical gender. She thus questions whether a default implemented as a rule is necessary and whether it is even…

Infants across cultures need to identify the characteristics of their native languages in order to become competent speakers. The means by which Spanish-speaking children learn to produce number-gender linguistic markers has not been sufficiently investigated. Thirty-eight three-year-olds were tested in Berko-like production tasks, in which they…

The study examined linguistic flexibility of Hebrew-speaking students from middle childhood to adolescence compared with adults on tasks requiring them to alternate between different versions of varied linguistic stimuli. Lexical flexibility was tested by constructing different words with a shared root and a shared prosodic template;…
